Cataract Surgery - YAG Laser Capsulotomy

A cataract is a clouding of the lens, the part of the eye responsible for focusing light and producing clear, sharp images. For most people, cataracts are a natural result of aging.

Following cataract surgery, between 6 months and 10 years, 20% to 50% of patients will develop haze of the membrane behind the intraocular lens (IOL) implant (the posterior capsule) which results in diminished vision.

The vision may be blurred, hazy, or is associated with significant glare and loss of visual acuity. This condition, known as posterior capsule opacification, is sometimes referred to as “secondary cataract”.

However, cataracts never recur following cataract surgery. Posterior capsule opacity may be thought of as a scarring process secondary to cataract surgery.

The condition is not preventable, but fortunately, it is treatable and nearly always restores or improves vision.


Posterior capsule opacity may be treated with an in-surgery or hospital out-patient minor Laser procedure known as a YAG Laser capsulotomy. In this procedure, a Laser is used to remove the hazy capsule situated behind the IOL implant.


YAG laser posterior capsulotomy is an out-patient procedure which requires no anaesthesia, because the procedure is painless.


Patients who have already had Cataract Surgery and start showing difficulty with reading, driving, glare or difficulty in recognising faces.

Risks, Complications and Side Effects

People who have a YAG Laser Capsulotomy have a slightly higher risk of developing a retinal detachment in the future. The rate is approximately 0.5% to 1.0%, but can be considerably higher in people who were significantly near-sighted before their cataract surgery.

Post-operative care, Convalescence

Following a YAG Laser capsulotomy procedure, patients may resume normal activities immediately. Most patients may expect their vision to improve within a day following the procedure.

As with any eye procedure, patients should contact their ophthalmologist immediately if visual acuity worsens or fails to improve.

Patients should anticipate some “floaters” following this procedure, however, this will likely resolve itself within one week.

Recovery time

Following a YAG LASER capsulotomy procedure, patients may resume normal activities.
